NAD+-protein-arginine ADP-ribosyltransferase

Protein mono-ADP-ribosylation is a reversible post-translational modification that plays a role in the regulation of cellular activities. Arginine residues in proteins act as acceptors. Free arginine, agmatine [(4-aminobutyl)guanidine], arginine methyl ester and guanidine can also do so. The enzyme from some, but not all, species can also use NADP+ as acceptor (giving rise to Nω-[(2'-phospho-ADP)-D-ribosyl]-protein-L-arginine as the product), but more slowly. The enzyme catalyses the NAD+-dependent activation of EC 4.6.1.1, adenylate cyclase. Some bacterial enterotoxins possess similar enzymic activities. (cf. EC 2.4.2.36 NAD+-diphthamide ADP-ribosyltransferase).
